Abstract

A mathematical model is proposed for a metal hydride plant, which can be used to utilize low-grade heat. As an example, the study considers a low-grade heat source, an HT PEMFC fuel cell with a high-temperature proton exchange membrane based on polybenzimidazole doped with phosphoric acid, with an operating temperature range 120–200°C. At temperatures near the lower limit of the operating range, the metal hydride utilization cycle appears preferable to the traditional Rankine cycle.

模拟带有高温质子交换膜的燃料电池中的金属氢化物利用循环

摘要针对可用于利用低品位热量的金属氢化物工厂提出了一个数学模型。作为一个例子，研究考虑了一种低品位热源，即带有基于掺杂磷酸的聚苯并咪唑高温质子交换膜的 HT PEMFC 燃料电池，其工作温度范围为 120-200°C。在接近工作温度范围下限的温度下，金属氢化物利用循环似乎优于传统的朗肯循环。

期刊介绍： High Temperature is an international peer reviewed journal that publishes original papers and reviews written by theoretical and experimental researchers. The journal deals with properties and processes in low-temperature plasma; thermophysical properties of substances including pure materials, mixtures and alloys; the properties in the vicinity of the critical point, equations of state; phase equilibrium; heat and mass transfer phenomena, in particular, by forced and free convections; processes of boiling and condensation, radiation, and complex heat transfer; experimental methods and apparatuses; high-temperature facilities for power engineering applications, etc. The journal reflects the current trends in thermophysical research. It presents the results of present-day experimental and theoretical studies in the processes of complex heat transfer, thermal, gas dynamic processes, and processes of heat and mass transfer, as well as the latest advances in the theoretical description of the properties of high-temperature media.
